  8. 8. Cutting and Slicing ToolsCutting and Slicing Tools (Knives, Box Cutters, Scissors, Razor Blades, etc…)(Knives, Box Cutters, Scissors, Razor Blades, etc…) Safety Gloves – Protection against accidental cuts and vibration A Sharp Blade Is Safer – When dull, a blade can slip from the object being cut and cause a serious injury. Cut Downward – Always away from your hand. Put It Back – Never leave a cutting tool lying on a table, chair, sink or desk. There are only three places that a cutting tool should ever be 1) in use, 2) stored safely in a drawer, tool box, in a knife rack, or, 3) in the dishwasher (blade down, handle up) 8 Never put knives in a sink full of soapy or dirty water. Someone could reach into the water and severely cut their hand.

Wipe Away From The Sharp Edge – if you need to wipe or clean material off the blade, always wipe away from the sharp edge. Never Touch The Sharp Edge – Always use a piece of paper to test the sharpness of a knife – NEVER use your fingers! Never use a knife as a substitute for other tools – such as a screwdriver or bottle opener. 9

  23. 23. INTRODUCTION OF GRINDINGINTRODUCTION OF GRINDING Whether they are portable or fixed, grinding wheels are designed to operate at very high speeds. If a grinding wheel shatters while in use, the fragments can travel over 300 miles per hour. The potential for serious injury, material damage and other losses from these shooting fragments is great. To ensure that grinding wheels are safely used in your workplace, know the hazards and how to control them. 23
